Considering Solar PV Training In The UK

It is by using natural resources such as tidal or wind energy – collectively known as ‘Green Energy’ – that we could meet our daily energy needs. They’re all considered naturally able to replenish – and thereby ‘Green’. It is easy to think that we may be travelling back in time when we think of items such as wind power and windmills. Generally, this is the result of using up to date ideas, specifically those that are planet friendly and eco-efficient.

In the home environment, one can see examples such as Solar Thermal and Solar Water Heating Collectors. To gain electricity from roof panels you would need solar electrical panels (PV’s). Following on from this is a process known as Biomass Energy – which includes Boilers burning wood and other fuels. We now also have Ground Source Heat Pumps – which draw out the heat left by the Sun. Finally, we have two of the most traditional forms of energy generation that have gone through some resurgence over the last few years; these being Wind Power, Wind Turbines and Hydropower (including Water Wheels.)

Thermal Solar Energy Systems: Typically referred to as Solar Energy this is mainly made up of two types of Solar Panels – each using different methods to achieve similar results. To begin with, we have the concept of drawing energy from the Sun to heat water – known as Solar Water Heating Collectors. Additionally, there is the method of converting solar radiation into electricity known as Photovoltaic – or simply Solar Electrical panels. Solar Panels themselves need to be away from all light blocks, and should be on south facing roofs at angles of 30 degrees from the horizontal plane.

In the UK, Solar Water Power is now one of the most sought after forms of Solar Energy. With the ability to provide almost half the annual need for hot water in the house, Solar Water heating systems are very important. The cost of fitting depends on whether you do it yourself (500 to 1500 pounds) or whether you get a professional fitter – in which case it will cost between 2-5k overall.

Biomass Energy Based Systems: Historically, this has come from plants and animals, though nowadays this also includes new genetcially engineered ‘energy crops’. Considering its ability to produce energy in the form of heat and electricity, this type of energy is extremely flexible. Furthermore, within the European Markets, the UK is one of the central producers of Biomass fuels. Considering all this, and the relative lack of C02 produced, makes the whole process highly green overall. Much of the UK wood crop is sustainable, in order to ensure that C02 produced during any heating process is absorbed.

‘Energy Crops’ trees such as Willow and Poplar play a major part in the process – under the banner of Short Rotation Coppice (SRC). Of equal importance is the production of perennial grasses – because of their yield of dry matter. Whilst Agricultural and Municipal waste may be lesser known, they are essential to the whole process. One natural offshoot of agricultural work is Agricultural Waste. Municipal Waste such as food or wood can also be utilised as a biomass product.

Geo-Thermal Energy Based Systems – This is primarily the heating of the Earth (mainly from the sun) and can be utilised in electricity and warm water production. In the UK, we are lucky that we can both heat and cool buildings from the ground source temperature of around 12 degrees. These heat pumps do need some power to operate; but for every one unit of energy they use, they generate four units of energy in return. Heat source pump energy can go one step further (by gaining a 100 percent return) if the energy to power them comes from items such as wind turbines or solar electrical panels.

Wind Energy: The use of wind as a source of energy has been going on for thousands of years, especially in milling grain and pumping water. However, in more recent times there’s been the option to recover the energy for its own sake – and deliver this either to a home unit or to the local power grid. The UK is considered as one of the best sources of wind generation within Europe. It is interesting to note that whilst we can produce 10 percent of our entire power requirement from wind power, at present we only produce 1 percent. Instead of producing electricity at a rate of 2-10p per kWh, we could be generating at 2p per kWh. From this, the estimation of the cost recovery period is around 6-9 months overall.

Finally, we have Hydropower; an area in which the UK does well within Europe. Having said that, the art of using energy from moving water (just like wind power) is very traditional. In total, this could produce something like 2 percent of all electricity required in the UK.

Using a turbine, a Hydropower system can transform the energy of water into other forms. Utilising natural river runs, or water drop-offs (through dams,) the turbines can work without a reservoir of water. A ‘Micro-Hydro’ system creates energy through the use of dams and sluices (that are no longer a part of the national distribution system.) Having been reviewed recently, this form of electricity supply could provide 200mW of the UK capacity. Installing systems like this could cost between 200 pounds and 3k per kW of energy created.

‘Green Energy’ is growing – mainly due to the demands of the Western World. That said, the UK is well placed – especially in the domestic sector – to take full advantage of the items above.

Once again, it is the Electrician and Plumbing trades that are set to capitalise on the domestic installation process. Grants and financial aid is also set to increase within the EEC and the UK – as ‘Green Energy’ gets ever higher status. As a new industry, there are a range of new certificates to gain. To cover both ends, you could consider electrical or plumbing training along with green systems.
